Even Her Maj couldn't resist a peek at the bling. The golden disks are decorated with citrines, and the blue enameled centers bear the coat of arms of Australia. They're topped by St. Edward's Crown, and the blue ribbons are decorated with golden wattle flower designs.

Alas, though HM was sporting some brooch bling of her own, I haven't been able to make it out. Something involving pearls. She's also still in "week off" mode, with her simple pearl studs instead of her usual pearl and diamond earrings and her black strap watch.
